强流质子加速器束流剖面分布及束晕测量系统设计
Design of beam profile and halo measurement system for high-intensity RFQ accelerator
摘要
Abstract
The beam halo generation in a high-intensity proton radio frequency quadrupole(RFQ) accelerator is one of the key issues, as the beam halo will probably result in beam loss in the downstream linac.A special beam transport line and the measurement system are to be built to study the beam halo generation in the accelerator driven subcritical system(ADS) RFQ accelerator.The measurement of the beam profile, especially the halo distribution is the core of this study.In this paper, the layout of the detectors in the beam transport line is presented.The mechanical design and simulations of the detectors are also presented,including the thermal simulation and material selection of the scanning wires, the design and R&D study of the driving and control system of the detectors, the design and simulations of the signal readout circuit, as well as the interface with the control system.关键词
